METHOD OF MAKING SOCKET MEMBERS OF SNAP-FASTENERS.

Specification of Letters Patent.

Patented Dec. 31,1912.

Application filed August 16, 1911. Serial No. 644,269.

One of the objects of my invention is the provision of a method of constructing the socket member of a snap fastener whereby the same may be made from a single integral plate of suitable material with the parts of the said plate so arrangcdand related with respect to each other that the saidsocketmember possesses not only the necessary resiliency and holding properties and qualities to enable it to cooperate satisfactorily and practically with the ball member of a snap fastener but will also possess the properties of strength, rigidity and neat-ness.

A further-object of my invention is the provision of a method by the employment of which the construction of a socket member of a snap fastener is simplifiecLandcheapened, so as torcnder it possible to furnish a strong, durable and efficient socketr'mei'nbe-r at a minimum cost.

In the accompanying drawings, to which reference may be had for a clearer and more comprehensive understanding of my invention, l have illustrated the various steps .whiclrmay be employed in the construction of a socket member of a fastener embodying my invention, but it should be understood that the shape or pattern of the plate from which the said member of the fastener is constructed and also that the steps as described herein may be Varied within the scope of the claims without departing from my invention. r

In the draWing,-l igui-s 1 is a plan vlew of a plate formed into a pattern or blank from. which the socket member of the fasvr may be constructed;v Fig; 2'is a plan 1, of the same after the ends of the or projections shown in Fig. l have llv: Fiat is a it 'n. s

a plan view of the said member showing the outer edge portion thereof turned at substantially right angles to the plane of the central portion of the plate; Fig. 5 is a transverse sectional view on the line 5-5 on Fig. 4; Fig. dis a top plan view of the socket member showing the upturned outer edge port-ion in Figs. 4 and 5 turned down into more or less proximity to the central portion of the plate with the ends of the prongs projecting through the central opening therein; Fig. 7 is a transverse sectional view on the line 7-7 of Fig. 6; Fig. 8 is a plan view of one side of a finished socket member of a fastener; Fig. 9 is a plan view of the opposite sidethereof; and Fig. 10 is a transverse sectional view on the line 1O10 o-f Fig. 8. 4

In the construction of the socket member of a fastener in accordance with my invention, I take a plate of material cut or othcrwise fo-r'lnedso as to be provided with projections which, after the plate has been bent and shaped to form the finished socket member of the fastener, constitute the spring acting parts thereof for engaging and holding the ball member of the fastener. Such a plate is illustrated in the drawings in which 1 designates the main or body port-ion thereof having projections 2 located at intervals around its peripheral edge. The said projections may be pointed as indicated in the drawings, the widest portions of said projections being situated a short distance from thepoints of connect-ion thereof with the peripheral edge of the body portion 1 of the plate. Portions of the said projections and of the adjacent edge portion of the plate upon opposite sides of each of said projections are cut away to form notches 3 as illustrated. The portions of the edge of the plate 1 between the projections 2 project somewhat and preferably are rounded.

However, it should be noted here that my inof fact the notches 3 may be omitted but their presence ,is preferred in order to'remore. some of the excess of metal when the 1 3.3.1116 is bent" and turned inwardly toward the center of the plate in the formation of the socket member.

After the plate has been cut or 'otherwise formed into the shape illustrated in Fig. 1 the intermediate portions of the prongs are bent laterally as indicated at 5 and the ends of the said prongs are bent during the same operation into directions very ,nearly at right angles, as indicated in Fig. 8, to the plane 'of the central portion of the plate. By bending the ends of the prongs in the manner illustrated and described in the last preceding paragraph I am enabled'to em--.

ploy prongs of greater length than could be employed if the said ends were not so bent. v

After the prongs have wise formed to the shape indicated in Fig. 3 of the drawings, the outer edge portion 7 of the" plate 1 is bent laterally until it occupies an angular position with respect to the plane of the central portionof thesaid plate. "7 with respect to theplaneoftheplate may The angularity of the edge portion be varied, but most probably it usually will be at a right angle, or very nearly so, to the A plane of said plate. The relative-positions of the parts at this point in the manufacture of the socket member are illustrated in Figs. 4; and5 of the drawing. Although the circular hole 8 at; the central partof the plate 1 may-be formed at any convenient time during the construction of the socket member of the fastener, I may form the same simultaneously with the bendingup of the plate into the form shown in Figs. 4 and 5.

As a further step. in the operation of con structing the socket member of the fastener according to my invent-ion. the outer edge portion 7 and the projections 2 are bent down from the positions shown in Figs. 4 and toward the central part of the plate 1 so that the points or portions 6 of the said projections extend through the socket hole v or opening 8 as shown in Fig. 7; From 'the positions of the said parts as illustrated in Figs. 6 and 7 the edge portion 7 and the basal portions of'the prongs 2 are broughtinto position nearer to the central portion of the plate 1 (which constitutes one side of the finished socket member) and the ends 6 of the said prongs 2 are bent over and aroundthe edge of the hole 8 into thepositi'on indicated at 10. in Figs. 9 and 1.0 of the drawings. v 7

By the employment of my new'metho'd of constructing the socket member of a fastener the ends of the projections 2 are bent and extended through and around the edge of the opening 8 in the central part of the plate 1 in such manner and relation to each other and to the edge of the said socket that they may yield outwardly for the purpose of permitting the insertion and withdrawal of the head or stud of the ball member of a been bent or other I 'between the projections 2 are of such extent that when the socket member 01 the fastener is coinpleted the opposite edges of the said projections are in close contiguity with the result above stated, but it should .be understood that my invention is not limited to a method in which the said projections are located in such definite relation with respect to ,each other. On the contra-ry the intervals between the said projections. may be varied and of such extent that when the outer edge portion of the plate and the said projections are bent over into the positions shown in Figs. 9. 10 and 11, in which the outer ends of the prongs are bent over and around the edge of the hole 8 through the centerof the plate 1, theedges of the said projections ,will not lie. closely contiguous to or in contact with each other as isillustrated in' the drawing but may be separated from each other by greater or less distances or intervals. It should also be understood that the shape or contour of the notches 3 may be varied as-may'be 'desired and as may be found practicable by manufacturers or othersconstructing socket members of snap fasteners according tomy. invention, and also that the shapes of the said projections may be varied.

Having thus described my ifnvention, I claim':"'

p Q. The method of making the socket member of a snap fastener which consists in taking a plate of suitabledimensions having-projections at intervals .on its edge and bending the said projections laterally and inwardly into operative relation with respect to the said plate and extei'iding the ends of said projections through an open ing in the said plate and bending the same around the edge of said opening.

3. The method of making socket members of snap fasteners whichconsists in forming a plate with pri'ijections at oppositely disposed points on the peripheral edge of said plate and the said plate also having a tentral socket hole or opening therethrough and then bending the said projections laterally and inwardly toward the center of the said plate and projecting the ends thereof through the said socket hole or opening and bending the said' projections around the edge of said hole or open ng maintaining the inner surface of the bends in spaced relation to the edge of said hole or opening.
